Hi Tim, does not look like that one, it has a flat sheet bi-metal wound spring inside the tube on one end, opposite the tube direction. At the other end inside the tube are 2 clam shell looking parts that are together when cold, and split open in the center when hot, these clam shell parts look cast, not sheet brass. will try to take a picture when i can get near the tractor in a couple of weeks. It's a 48 8N
